Jon, it's true, those government owned facilities have no problem getting the okay for expansions/new mills and many of them deal with no environmental regs at all.
But like CZ said, it's still happening in the US, and has been for the last few decades.
The 'not really' new one in Mobile, AL is a foreign owned facility, but provides decent jobs/revenue.
Sadly it takes a few years to get nearly anything approved, then a couple more to get it up and running.
Certainly less 'hoops' for acquisitions and upgrades.
Thankfully there are still a few politicians that realize the economic impact that one of these facilities can provide.
Believe it or not, Nucor has a mill in downtown Seattle, Washington.......
And is THE largest recycler in North America.
Oh..... and I know some steelworkers that buy, shoot, and collect double guns.
